Russia questions whether U.S. complies on nukes

MOSCOW -- Russia challenged U.S. compliance with a key nuclear arms control treaty on Monday and warned the Trump administration's new nuclear strategy lowers the threshold for using atomic weapons.

The dire assessment came as Moscow said it has met its own requirements under the New START agreement signed in 2010 and entered into force a year later. It restricts both the U.S. and Russia to 1,550 deployed strategic nuclear warheads on a maximum of 700 deployed intercontinental ballistic missiles and strategic bombers. The deadline to verify both countries' compliance was Monday.

The Russian Foreign Ministry said it now has 527 deployed intercontinental ballistic missiles and strategic bombers. It gave a tally of 1,444 strategic nuclear warheads. The U.S. reported it has been in compliance with the limits since August.

Russia acknowledged the U.S. position on meeting the targets, but voiced concern about the U.S. reconfiguring some submarines and bombers to carry conventional weapons. The Foreign Ministry said it doesn't have a way to confirm the reconfigured hardware was rendered incapable of carrying nuclear weapons.

Washington also "arbitrarily converted" some underground missile launch sites into training facilities, which wasn't spelled out in the treaty, the ministry said. It urged the U.S. to work with Russia to resolve such matters.

The U.S. State Department insisted America was fully adhering to the deal.

"To meet the central limits of the treaty, the United States developed and utilized conversion procedures in full compliance with its treaty obligations," it said, adding it would cooperate with Russia to "address technical questions and issues related to the ongoing implementation of New START."

Russia-U.S. ties have been miserable for several years, but nuclear weapons reduction has been a strong point. The former Cold War foes have clashed most notably over Russia's conduct in Ukraine, the Syrian civil war and allegations Moscow meddled in the 2016 U.S. presidential election. The Trump administration's pivot to a new nuclear strategy could now affect arms control cooperation.

Last week, the Trump administration announced it would continue much of President Barack Obama's nuclear policy, while adopting a more aggressive stance toward Russia. Russia must be convinced it would face "unacceptably dire costs" for threatening even a limited nuclear attack in Europe, the new policy states.

The Pentagon-led review made clear the administration's view Russian policies and actions are fraught with potential for miscalculation, which could lead to an uncontrolled escalation of conflict in Europe.

It specifically pointed to a Russian doctrine known as "escalate to de-escalate," in which Moscow would use or threaten to use smaller-yield nuclear weapons in a limited, conventional conflict in Europe to compel the U.S. and NATO to back down. Consequently, the review said the U.S. would modify "a small number" of existing long-range ballistic missiles carried by Trident strategic submarines to fit them with smaller-yield nuclear warheads.

Russia slammed the U.S. report, saying it was founded on false assumptions about Moscow's intentions and contained worrying modernization plans.

The U.S. Nuclear Posture Review puts "in question our right to defend ourselves against an aggression that threatens the country's survival," the Foreign Ministry said in a weekend statement. "We would like to hope that Washington is aware of the high level of danger when such doctrinal provisions move to the level of practical military planning."

The ministry said Russia's military doctrine envisages the use of nuclear weapons to deter an aggression threatening "the very existence of our state." It said Washington, however, took a no-limits approach toward using nuclear weapons in "extreme circumstances" beyond defense against military operations.

"Even military scenarios are presented so ambiguously that it seems like the U.S. planners may view practically any use of military capability as a reason for delivering a nuclear strike against anyone they consider an 'aggressor,'" the ministry said.

It said U.S. plans to develop new low-yield nuclear weapons "will greatly increase the temptation of using them, especially considering the right to a disarming first strike as set out in the new U.S. doctrine."

"Assurances that the implementation of these plans will not lower the nuclear threshold can at least be interpreted as a desire to delude the international community," the ministry said.

"It is even more frightening that the U.S. military and other national security professionals firmly believe in their ability to model conflict scenarios that involve low-yield nuclear options. Quite to the contrary, we believe that this dramatic lowering of the threshold conditions can provoke a nuclear missile war even in a low-intensity conflict."
